Walchli Reservoir in Umatilla County: How and When to Fish It

• Overview

  In Oregon, Walchli Reservoir belongs to Umatilla County. Country round the bank runs to dry rangeland. At 23 acres it is the sort of place you fish for an evening rather than a day. Our Umatilla County list holds plenty of bigger water. Hermiston sits 5.3 miles from here and is the nearest stop. The big place round here is Tri-Cities, 27 miles distant. A county line runs close by, so local bylaws can differ within a short drive.

• Where to Fish on Walchli Reservoir

  We hold no survey for this water; read the slope of the shoreline instead. Points where the flooded channel swings in are the reliable ones. Draw-down through summer strips the margins, so follow the water out. County-wide records name rainbow trout, bridgelip sucker, Chinook salmon and largescale sucker. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Read Walchli Reservoir for ten minutes before the first cast goes out.

• Seasonal Patterns

  Expect July to average close to 74°F, with January the cold end at about 34°F. The freeze here is occasional rather than annual. It is not guaranteed from one year to the next. April and May are the settled weeks, with October close behind. Anyone fishing Walchli Reservoir regularly works to that calendar.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. You will be walking about half a mile from the nearest car park. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Parking space is the usual limit rather than the bank itself. Signs go up and come down, so check on the day. For a change of water, Cold Springs Reservoir is 1.6 miles distant. Treat Walchli Reservoir as unsettled until someone local tells you otherwise.
